Or you can just configure your GitLab CI to work and an older version of the script by just pointing the right yaml URL at that versions in the configs, or am I missing something? > > Due to that, I'm not convinced that such kernel CI files should be > hosted at the Kernel tree. > > IMO, this should be stored on a separate repository hosted at > kernel.org, using Semantic Versoning (https://semver.org/) - e. g. > when there are incompatible changes, major version number will be > increased. A key benefit of having it in-tree is the test expectation list, as seen with DRM-CI. This allows developers to track the state of drivers and progress over time by showing which tests are expected to pass or fail at a given point in history. (From what I see in DRM-CI, this adds a considerable amount of value.) Please check the VKMS patch in this patchset. Also, if we keep this tool out of tree, I’m concerned that subsystems like DRM and Media will continue not collaborating—each currently has its own solution when the base could be shared and reused. All static checks, build processes, and boot mechanisms are fundamentally the same, with only minor differences that are customizable. Other subsystems could use just the base or build their specific configurations/tests on top of it. Having it in-tree sends a message: "You can create your own GitLab CI pipeline, but why not use this existing one, contribute to it, and collaborate for everyone's benefit?". Since it's under the tools/ folder, it’s a helper tool. Make sense?
